Continuity mistake: When Sylvester Junior is turning the wheel to pump oxygen into his father's diving suit, he spots a worm and starts following it, walking away from the pump. But when Sylvester bangs on the tank glass telling him to start pumping, we cut back to Sylvester Junior and he is back near the pump again.

Trivia: When Sylvester and Junior are watching television at the start of the cartoon, they see a local fisherman called Treg Brown who landed a big one. Treg Brown was the sound editor who was responsible for the sound effects in the Warner Brothers' Merry Melodies and Looney Tunes cartoons.
